Letters Patent No. 98,556, dated January 4, 1870.

vIIMPRO'V'ED WASHING-MACHINE.

` The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, GEORGE E. OnAMBERLrN,-'of New York, in the, county of New York, and State of New York, have invented certain new and useful Improvements in VVashing-Machines; and-I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to" the letters of reference marked thereon, which form a part of this specification.

Devices hitherto employed for reversing the cylinders of washing-machines, have consisted eitherin the employment of two belts, straight and crossed, arranged to drive the shaft in opposite directions, by being shifted horizontally from a loose to a fast pulley, or by one belt similarly shifted, operating directly on the shaft in one direction, and, through a system ofgeaiing, causing the driving-simil: to revolve in an opposite direction.

The object of my invention is to obviate all complicated gearing or machinery; and i it consists in the use of but one belt, or crank for bami-machines, which drives the cylinders of one or more washing-machines in opposite directions alternately, without being shifted horizontally, and withthis outchangng the direction of the revolutions of the driving-shaft, thereby savingpower and the rapid deterioration of belts and shifting-gein` experienced in devices hitherto employed.

In order to enable ot-hersskilled in the art to which my invention appertains, to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation, and

Figure 2, a plan view of my machine.

Figure 3 is a longitudinal vert-ical section of the cylinder-gudgeon, through which the reversible motion is conununicated to the cylinder.

A represents the tub of the washing-machine, with` in which is the cylinder B, revolving upon journal t at one end, andupon the gudgeon b at the other end.

The gudgeon b passes `thrcnigh a metal hub, d, secured in the side-of the tub A, and is at its outer end provided with a pinion, e, keyed or otherwise iirmly -secured to the same.

Between the pinion e and the Harige-plate of the `hub d, upon the outer end of hub D, is' placed a loose anti-friction roller or pinion, j". 'k

Around the pinions e and j? is placed a yoke-rack, C, having cogs on its inside, on both the upper and lower sides, the cogs on the lower side gearing with thc pinion-e, and those on the upper side with the roller f. This latter roller, being of a diameter somewhat larger than that of the pinion c, prevents the upper cogs of 'tt-Lat.. are aha7/a7@ the yoke-rack from catching in any manner in the cogs of the pinion e.

The yoke-rack C is made in one piece with a rod,- D, which connects with a crank or wrist-pin, t, upon the side of a large cog-wheel, E, mounted upon the shaft G, having its bearings in suitable bracketsl on the rear side of the tub A. i

The shaft G, with its wheel l), obtains its rotary motion from a` pinion, I, upon the primary drivingshaft H, which is revolved in one direction,either by a belt around the pulley J, or by hand, by means of the crank K.

It will readily be seen that the main shaft revolv-i another revolution inthe opposite direct-ion, and so on, constantly alternating from one sideto the other.'

The operation of the yoke-rack U, with the pinion e and crank-pin i, causes the cylinder to remain an instaut at rest before it commences its movement. This movement is first slow, and gradually increases until the cylinder hasvperformed half a revolution, when it decreases, until, when the revolution is completed, the cylinder is at rest again, when it commences a similar movement in the opposite direction.

The cylinder B is made in any of the known and usual ways, of. slats, and having a lid through which the clothes are put in. p

. The pinion I is placed loosely upon the primary shaft H, and is thrown in and out of gear by means fo a feathered collar, L, in any suitable manner.

Upon the shaft Gare placed one or more o thcrcranks M, connect-ing with the cylinders of` other washingmachines, but said cranks are so arranged that but one cylinder' in the sexies willbe reversed at the same time.

Upon the side of the tub A is secured a bar, N, which connects the hub cl with the bracket, supporting the crank-shaft G, and thence with the foot or foundation, forthe purpose of relieving the hub from the strain of driving the cylinder by means ofthe crank, the motion having a tendency to draw the two shafts together and thrust them apart alternately. This ymotion is also superior, from the clothes being thrown across and mpinging with greater force ou the opposite side of the cylinder by thc accelerated velocity of the same, producing a more constant agitation and equal act-ion on all the clothes. Being more simpie and direct, it is less liable to get out of repair, and more durable than former devicesg l he same device may be used on any other machine, for reversing the motion, without changing the direc-- tion of the revolution of the main shaft.

Ffa-ving thus fully described my invention, 3. In combination with the central hub d, and the Vhat I claim as new, and desire to secure by Letbracket supporting the driving-shaft` G, the bar N, sub.- t-ers Patent, is stantialiy as and for the purposes herein set forth.-
